Abstract
A musical instrument having a general body outline similar to that of a saxaphone. A front key panel having a plurality of keys mounted thereon is located for easy fingering access to the keys which are in the same general location as the fingering keys on a saxaphone. A rear control panel is provided for mounting instrument voice characteristic and special effects controls. A mouthpiece is provided for engagement by a player's mouth and a pressure transducer is carried in the mouthpiece for communication with the player's breath pressure and for producing a pressure signal corresponding thereto. The pressure signal is connected to a pressure attack circuit for producing a pressure attack signal. Finger pressure applied to predetermined combinations of keys provides predetermined combinations of key pulses for connection to a key decoder. The key decoder produces a binary output corresponding to the predetermined combinations of key pulses which ranges from zero to 1111. A digital to analog converter receives the digital signal and provides an analog tone signal corresponding thereto which is connected to the input of an exponential voltage controlled oscillator. The voltage contro…
